Greno 11kv 12kv Sf6 Gas Load Break Switch

SF6 load break switchesare designed for switching circuits with currents up to 630 A in 6 kV, 10 kV, and 20 kV/24kV/ 50 Hz three-phase A.C. networks.Professional service ,win-win business
Featuresoftheproducts:
1)Designed for our GSM serie AIS ringmainunit(RMU)switchgearandcouldalsofittoall kinds of similar switchgears.
2)Insulation ability for arc-extinguishing is increased(when switchgear is at open status) because SF6 gas was filled with0.03Mpa~0.04Mpapressure
Safely make the whole size smaller.
3)Best material:Thecoppercontactercontains more than99.95%Cucontentandspecialproduction processguaranteedtheabrasionrigidity.We called this materialnamedT2copper.4)Increased phased distance:210mm,particulardesignlengthenedairandcreepagedistance.
5)Strictly control quality we chosethebestqualityepoxyresinalthoughitwasexpensive.
Making a belt transect with epoxy resin to test before every production is a must.
According to test datas ,the majormaterialquality(suchas bendingstrength,tensilestrength,impactstrength etc) is well controlled.6)Internal contactterminals are ofpermanentmagnetismmaterial.
The arc becomes thinner and thinner thus naturallyexthinguish in SF6 gas whenLBSswitches to openposition.
